SPECIFICATION forming part of Letters Patent No. 563,742, dated July 14,1896.

Application filed March 16, 1894:. Serial No. 503,832. (No model.)

To (0Z5 whom may concern;

Be it known that I, ALBERT M. CLARK, a citizen of the United States,residing at Ann Arbor, county of Washtenaw, State of Michigan, haveinvented a certain new and useful Improvement in Valves; and I declarethe following to be a full, clear, and exact de* scription of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

My invention relates to devices adapted to automatically control theadmission of water into tanks, and particularly to fl Tish-tanks forwater-closets. Its object is to provide means for admitting anddischarging the water and flushing the bowl.

It consists in a novel inlet-valve and attachments, novel valve fordischc rging' or flushing the water, and means connect-ing theinlet-valve and the discharge-valve whereby the float operating theinlet-valve unlocks and closes the outlet-valve. Thus my invention,while covering novel valves distinct in themselves, it also includesmeans whereby they are caused to operate together in complete action ofthe device.

In the drawings, Figure 1 is a vertical sectional view of a flush-tank.Fig. 2 is a vertical sectional view of inlet and outlet valves of aflush-tank. Fig. 3 is a view showing the case of the inletvalve with itstrunnions. Fig. l is a vertical sectional view showing the engagement ofthe bailwith the case and its trunnions. Fig. 5 is a view showing thecon struction of the bail. Fig. 6 is aview showing a float-rod and abail formed integral therewith. Fig. 7 is a plan of the flushinglever.Fig. 8 is a perspective of the valve used in a variation. Fig. 9 is anelevation showing the case of the valve used in the form shown in Fig.(i. Fig. 10 is a view showing the flushingdever at the top of the tankand an after-fill. Fig. llis a sectional view of the top of thevalve-stein. Fig. 1211s a plan view of the form shown in Fig. 10.

In the drawings, Ais a tank; B, the inletvalve; 0, the outlet-valve; D,the float.

B is the case of the inlet-valve.

E is a removable and reversible seat, the seat proper being the upperend of the stem the angle of the float-rod with bail.

portion 6. The seat E is held in the case by the union-nut E, screwed onthe bottom of the case. This forces the seat E upward, so that theannular flange 6', formed integral with the seat at its center, comesagainst the shoulder Z) of the case. The stems of the seat E being ofequal length, it can be removed and reversed, and the annular flangewill bringit to the same position in each case. The object of makingthis seat reversible as well as removable is to provide against theexpense attending repairs due to the wear of the seat at E. As the stemF of the valve is usually provided atf with a rubber packin g, thepresence of sand and other grit tends to wear away the end of the seat.

By the use of my construction, all that is necessary to repair the valvethe first time is to remove the seat E and invert it. After the firstrepair the plumber has only to insert a new seat in place of the oldone. This change is made by simply unscrewing the union-nut E, insertingthe seat,and returning the nut.

The seat E is hollow, and the water-passage through the valve is thusthrough the seat, and the water-inlet passage is closed by forcing thestem F down on the seat.

The stem F is provided with the head F, formed at the upper edge on acircle at f.

G is a bail pivoted to the trunnions a on the case, swinging over theare of the stem. The bail and the stem are made of such length, and theare so formed, as to bring the stem downward upon the seat E when thebail is vertical or approximately so, thus locking the stem when theparts are in this position. If desired,the bail maybe provided with theroller g, or any other suitable antifriction device.

D is the float-rod, engaged with the head (Z. To provide for adjustment,I pivot this head to the bail and employ the adjustingscrew d. The headhas an overhanging portion d against which the end of the screw acts.The movements of this screw adjust By means of this adjustment theinlet-valve may be closed with any desired depth of Water.

To avoid the expense of constructing my device and convenience inassembling the parts, I arrange to engage the bailG with the trunnionsby slipping it over the trunnions case is beveled at is to form a seat.

M is the valve, and M. an annularpacking,

at a position different from that in which it is usedwhen the device isin operation and then swinging it into the operating positions,

and so constructing the case, the trunnions, and the bail as to hold thebail on the trunnions throughout its operating positions.

Above the trunnions on the case I provide preferably of rubber, andprovided with an interior annular projection on, which fits in anannular groove in-the metal portion and holds the packing firmlyinposition on the discharging through the valve.

valve. The valve-stem consists of the vertical tube M This tube extendsnearly to the top of the tank and becomes an overflow-pipe, The tube isprovided at the top with thehooks at, each hook having an ovalopeningn'l, and an en trance-slot m. I I t N is a flushing-lever pivotedon the crossbar N This leveris weightedat it". On the weight n are thetrunnions if. I Thesetrunnions engage with the hooks m and enter thehooks through the slot m N is the chain with which the flushing-love isoperated. By drawing down on the chain the leverraises the tube M andopens the cut let-valve M. To-hold the valve open when the water isdischarging and flushing, I use the latch N, depending from the lever.This latch engages with the catch 1) on the case of the inlet-valve whenthe lever is drawn down to open the outlet-valve. This latch holds thelever down and allows the water to discharge until the float lowerssufficiently to swing the bail G until the cams g 9 force the latch fromthe catch 1). This allows the lever to rise and the outlet-valve toclose. The latch is provided at the lower end with a T a Thus the camson opposite sides of the inlet-valve case each act on the latch todisengage it. The amount of water that will be discharged is regulatedby the adjustment of the float-stem on the bail.

The construction shown in Fig. 10 for the top of the valves stem or tube1 2 at the connection with the flushing-lever is designed to beassembled without fitting the castings. IVhen the valve M is closed, theweighted end of the lever N rests on the stem R, and the position of thecap K is such as to hold the trunnions in the hooks.

I provide the hollow stem M with means for preventing the gurgling,consisting of the weighted cushioncap K. This cap is weighted by andsupported on the stem R,

wvhich extends down into the hollow stem or thevalve and rests upon thepilot M" when thevalve is closed, and is of such length as.

to raisethe cap from the top of the stem when IV hen. the stem .s

raised and the valve opened, the cap lies on I the stem and prevents thepassage of air into the stem. It is this passage of air that causes thegurgling. I I

Q is an after-fill passage into the overflow tube '1' and is closed bythe valve, g. This valve is held to its seat by the lever Q. This leveris operated by the float Q This float is made adjustable that it may beso set as 20 prevent waste. sage when the tank is flushed and the waterin a the tank discharged, and hold it open until the tank is partiallyfilled again. Theaftcrfill, passage is only large enough to permit a Itwill open the after-fillpassmall amount of water to discharge while thet supply of water is. to, be shut oii when it reaches a certainelevation in the tank; The

trunnions on the case, with. the segment a. are the same as those used.in the other construction shown, and the bail G is engaged with thetrunnions in the same manner. is a catch, cast integral with the case,having lugs on opposite sides, under which the curved arms f f of thevalve engage. Thus the valve is held in position on the seat withoutdrilling or riveting. This valve has a curved top over which the bailswings, and

on which it acts to close the'valve after the r manner before described.This valve and hail is applicable to horizontal as well as vcrticalinlets. In either case the bail is engaged with the case of the valvewithout drilling, tapping, or riveting and without machine work.

In Figs. 1 and 2 the flushing-lever is placed within the tank at thebottom instead of at the top, as shown in Fig. 10. Such construction maybe used with advantage, and I therefore show and describe the same. N isthe flushing-lever in this case and is pivoted at n. It is provided withthe oval opening W. as shown in Fig. 7. The opening is of sulficientsize to permit the stem M to pass up through it. The stem is engaged tothe flushing-lever by means of the lugs m one above and one below thelever on each side of the stem. To prevent the valve-stem from rotating,I employ the pilot-loop M rising from the valve-seat. This pilot passesbetween lugs m cast on the inside of the stem in pairs. In thisconstruction the latch a is pivoted to the end of the flushing-lever andengages with the catch 1) on the side of the case of the inlet-valveopposite from that shown in the other construction, but is forced fromengagement with the catch on the case by the cams g g in the mannerbefore described.

The combination of the bail pivoted on the case and the stem or valvehaving the curved top has the great advantage of securing the maximumresistance against the pressure of the water, as the bail, the valve,and trunnions, when the valve is closed, are all in the same line.

hat I claim is- 1. The valve, the head formed with the cam, the bailpivoted to the opposite sides of the case approximately on a line withthe center of the valve, whereby the force tending to open the valve isin line with the resistance, and the valve locked by the bail when setto close the valve, substantially as described.

The combination of the valve and case, trunnions on the case, the bailslotted to engage the trunnions and provided with re cesses thesegmental projections a, which In testimony whereof I sign thisspecification in the presence of two witnesses.
